Answer 2

Answer:

The man's original salary was Rs. $140000$.

Step-by-step explanation:

Given : Percentage increase in a salary = $10$%

                                   His new salary = Rs. $154000$

To find : The original salary of man =?

Solution :

• It is given that a man got $10$% increase in his salary.

                     His new salary = Rs. $154000$

• We have to find his original salary.
• Let, $x$ be the man's original salary.
• According to given condition, the equation becomes,

              $10$% of $x+x=154000$

              ∴ $\frac{10}{100} *x+x=154000$

                     ∴ $\frac{10x+100x}{100} = 154000$

                         ∴ $\frac{110x}{100} =154000$

                          ∴ $110x=154000*100$

                               ∴ $x=\frac{15400000}{110}$

                               ∴ $x=140000$

• ∴ The man's original salary was Rs. $140000$.
